Gusts of 70mph are also expected, which along with persistent downpours could cause yet more chaos and disruption.

A Met Office spokesman said: “Heavy rain is expected to develop early on Saturday and persist into Sunday. Given saturated ground and higher river levels, be aware of the potential for flooding affecting parts of communities, disruption to travel, and danger to life from fast-flowing deep water.

“50 to 80 mm of rain could fall quite widely with over 100 mm possible across prone areas such as Snowdonia .”

He added: “Southwesterly gales are expected, with gusts of around 70 mph possible around exposed coasts and over hills. This may result in some branches or trees being brought down.”

Meanwhile a yellow weather alert for rain that was issued today (Wednesday) remains in force until 9pm tomorrow (Thursday).

Natural Resources Wales (NRW) are warning that due to prolonged rainfall earlier this week that the ground remains saturated, meaning further rainfall will quickly find its way into rivers and streams resulting in flooding.

A red flood warning is currently in force for Bangor-on-Dee with river levels being above normal.

While there are also orange flood alerts in place for areas including the Lower Dee Valley from Llangollen to Trevalyn Meadows and Glaslyn and Dwyryd area in Snowdonia.
